I sometimes walk back into a public establishment, for a logical reason in myself, simply because I've  seen a person who looked curios to me. When I notice that they are no longer their as I enter and take my seat, I continue on. Nothing changes.

I've come a long long way.
When I was a little boy, I would breakdown in tamper-tantrums, because someone I cared about for no reason had disappeared,  never to be seen again.

(Hi, may I have a large coffee, please. That's all)
